+ * Supports:

+ *               number on top frame
+ *   - Opera 10: full stack trace with line and column numbers
+ *   - Opera 9-: full stack trace with line numbers
+ *   - Chrome:   full stack trace with line and column numbers
+ *   - Safari:   line and column number for the topmost stacktrace element
+ *               only
+ *   - IE:       no line numbers whatsoever
+ *
+ * Tries to guess names of anonymous functions by looking for assignments
+ * in the source code. In IE and Safari, we have to guess source file names
+ * by searching for function bodies inside all page scripts. This will not
+ * work for scripts that are loaded cross-domain.
+ * Here be dragons: some function names may be guessed incorrectly, and
+ * duplicate functions may be mismatched.
+ *
+ * TraceKit.computeStackTrace should only be used for tracing purposes.
+ * Logging of unhandled exceptions should be done with TraceKit.report,
+ * which builds on top of TraceKit.computeStackTrace and provides better
+ * IE support by utilizing the window.onerror event to retrieve information
+ * about the top of the stack.
+ *
+ * Note: In IE and Safari, no stack trace is recorded on the Error object,
+ * so computeStackTrace instead walks its *own* chain of callers.
+ * This means that:
+ *  * in Safari, some methods may be missing from the stack trace;
+ *  * in IE, the topmost function in the stack trace will always be the
+ *    caller of computeStackTrace.
+ *
+ * This is okay for tracing (because you are likely to be calling
+ * computeStackTrace from the function you want to be the topmost element
+ * of the stack trace anyway), but not okay for logging unhandled
+ * exceptions (because your catch block will likely be far away from the
+ * inner function that actually caused the exception).
+ *
+ * Tracing example:
+ *     function trace(message) {
+ *         var stackInfo = TraceKit.computeStackTrace.ofCaller();
+ *         var data = message + "\n";
+ *         for(var i in stackInfo.stack) {
+ *             var item = stackInfo.stack[i];
+ *             data += (item.func || '[anonymous]') + "() in " + item.url + ":" + (item.line || '0') + "\n";
+ *         }
+ *         if (window.console)
+ *             console.info(data);
